(0001450) slonopotamus 08-10-06 06:52	Sorry for duplicates, I was trying to attach example WAR.

(0001451) slonopotamus 08-10-06 07:12 edited on: 08-10-06 07:23	Resin 3.0.10 and 3.0.13 are affected too.

(0001454) anonymous 08-11-06 02:46	Actually problem is with Strings in EL expressions. This example produces same error: <?xml version="1.0" encoding="UTF-8"?> <jsp:root xmlns:tags="urn:jsptld:/WEB-INF/tags.tld" xmlns:jsp="http://java.sun.com/JSP/Page" [^] xmlns="http://www.w3.org/1999/xhtml" [^] version="2.0"> <jsp:directive.page contentType="text/html" pageEncoding="UTF-8" /> <html> <body>${"test"}</body> </html> </jsp:root>
